Conflicts: FusedRounds scenario brief and fixture comment, SmokeRoundsSteppedTests, and AetherDb's usage line keep both sides, with
DeathCluster renamed Cluster Cannon. GameData/Aetheria.cc is master's blob; range-falloff is rerun on it in the next commit.
This commit's catalog does not carry the falloff stats, so CatalogRole/falloff catalog tests do not pass here.
